About this check

What AI Essay Detector actually does.

Essay-specific entry point for educators, editors, and reviewers. AI-detection-as-grading is unsafe — but as a triage tool that prompts deeper conversation with a student or contributor, it has a place. The engine surfaces the patterns and lets you make the call.

How it works

  • 1Sentence-pattern regularity catches uniformly balanced clauses common in LLM prose.
  • 2Generic-transition scoring flags 'in conclusion', 'furthermore', and similar connectors at high density.
  • 3Claim-specificity weighs how often the essay uses concrete names, dates, and references.

When to use it

Real situations this page is built for.

  • A submitted essay is suspiciously polished for the author's known voice.
  • A draft matches a familiar LLM output structure exactly.
  • A peer-review reviewer wants a quick second opinion.

Limitations

Strong human writers — especially academic English — score similarly to LLMs. Never use this as the sole basis for an academic-integrity decision.

AI explainers
How accurate are AI text detectors?
AI text detectors have a high-profile accuracy problem — false positives on formal English, false negatives on humanized output. Here's the realistic picture.
AI explainers
Does Turnitin detect AI? Honest answer for 2026.
Yes, Turnitin has an AI detector — and yes, it has the same accuracy limits as every other AI text detector. Here's what it actually catches, what it misses, and what to do with the result.
AI explainers
What is an AI humanizer, and does it actually work?
AI humanizers rewrite ChatGPT output to evade AI detectors. Here's how they actually work, why detectors keep catching up, and what 'undetectable AI' really means.
AI explainers
Are AI humanizers really undetectable?
Tools promising 'undetectable AI' have a credibility problem. Here's what humanizers actually achieve against current AI detectors — and what they fail to hide.

Honest scope

What this detector does not do.

Naming the gaps explicitly so the score is interpreted in context.

  • Plagiarism against published sources (use a plagiarism checker for that).
  • Whether claims in the text are factually true.
  • Authorship attribution to a specific human writer.

FAQ

AI Essay Detector questions

Can I rely on this to fail a student?

No. AI-text detectors are unreliable as standalone evidence and should never be used that way.

What about Turnitin-style plagiarism checks?

Different problem. This page only checks AI-likelihood, not text reuse.

Does it work on creative writing?

It tries, but creative writing legitimately uses many of the same surface patterns as LLM output.
